NEED HELP // Programs unable to write files in documents

[RokasOnline]

Hello, I need help with my Windows machine. I have built my first custom PC, I first installed windows 10 without a key, later I bought a key for Windows 10 Pro and upgraded it.

The problem I have is that some of my software can't work properly, because they are unable to write in some directories.

I noticed this yesterday on two occasions:

01. A game Sid Meiers Civilization: I can't save the game. I press the save button, but it then does not appear in my documents folder, nor in the game itself. Also, every time I open the game, it is like it is opened for the first time because it clearly cannot save any preferences in that folder.

02. Software ZBrush: I literally can't open the software, because when I do, I get the errors, first one being:
Unable to save file C:/Users/Public/Documents/ZBrushData2018/ZBrushScratchDiskPath

And then it is followed by another error:
FILE WRITE ERROR: Sorry, the disk space is critically low. ...

I only have one 2tb SSD drive in my desktop and it is half empty right now.

I tried opening programs as an administrator, also tried messing with sharing options and unchecking read-only options for Documents folder, but nothing worked for me.

Also, when I open those locations, for example where the game saves files, it is completely empty, but I can create or modify anything inside it, so it seems like I have the permission to do so, but not when I run the programs itself.

I suspect reinstalling windows might help, but I really don't want to do that, as I would have to reinstall so many things again. Anyone have any ideas, please? Thank you

Thank you

Before you run the program, right click on the icon and choose "run as administrator", see if that helps/solves anything. Report back.

Tried it, doesn't help

 

Edit: It is because of the safe files, secured folders option in my BitDefender... Turned it off and it's fixed, wasn't Windows problem after all.
